Mitsubishi Electric has launched a new 11.2kW Ecodan air source heat pump to join the existing three monobloc models. The line-up for the self-contained outdoor units now boasts a 5, 8.5, 11.2 and 14kW to make Ecodan suitable for almost any situation. The new PUHZ-W112VHA model is a single phase, MCS-certified 11.2kW capacity unit that shares the ability to cascade up to six units of the same output, allowing Ecodan systems to offer a capacity range from 5 through to 84kW. With low maintenance and quiet running as recognised by the Noise Abatement Society, the unit operates with outside temperatures as low as -20°C and also offers a bivalent function, allowing it to be used in a hybrid situation with an existing traditional boiler.
